Its groove in which the rolls 18 travel is mathematically designed and of rather irregular shape having a concentric portion as shown in Fig. 5 so dis posed as to produce a special period of ignition. By virtue of the described arrange ment the transmission of power is efi'ected and the piston strokes are governed. Each cylinder and piston is operated independently from the others.

"The cylinder has on its outside a suitable number of ribs n1 for the purpose of effecting air cooling during the rotation of the motor. These ribs 21. are shown solely on one (.rylinder in. Figs. 3 and 4 and more or less than shown may be provided.

The outer spherical surface ofthe rotor and the inner surface of the spherical casing like the section of a sphere must have the same radius in all directions. For the purpose of ell'ecting a perfect packing between these spherical surfaces packing rings 22 are provided within the outer wall of the rotor. These packing rings are located in concentric grooves in said outer wall around the cylinder openings and the rings are finished on the outside so as to conform to the spherical surfaces. In this way a perfect packing is obtained and the same effect results as from the packing rings of a piston.

The exhaust device is located on the right side of the enlarged lower portion ofthe 1. As shown in Fig. 3 the exhaust gases *hrough a tube T his ,tubc Slll.EC'OUlll.-.l by a largeriube'fil shown to the left in said The gases streaming through the tube under pressure draw the reu'iaining gases emptying into 'tubeBl out with them. in this manner the exhaust gases are completely removed. Ifdcsired the motor may be provided with a water cooling jacket which may be of any approved construction.

The operation of the motor is substantially as follows: Assuming that the rotor turns from the left to right in Fig. 3 and that a cylinder with piston passes the conduit or fuel inlet 5 then the explosive fuel mixture is drawn into said cylinder while the piston performs the inward or forward stroke. This is effected by the movement of the roll in the eccentric cam groove. Upon further rotation otf said cylinder it reaches'a point where the adjoining portion of the outer spherical casing closes oil the explosive gas i'nixture within said cylinder, and upon further rotationthe gas mixture is compressed owing to the changed location of the roll in the eccentric can] grow-e. the piston thus performing; its outward or return stroke. ll' hcn the piston reaches approximately the top center of the motor-casing where a s ark plug located the n'11xtui'c 1s ignited.

The expansion oi? the gases due to the (our bustion of the fuel forces the piston to peripeo zio form an inward or forward stroke whereby the piston rod actuates the pivoted lever arrangement and forces the roll against the respective portion of the irregular cam groove, which is so curved that a jiifevolution of therotor is effected. Upon further rotation of said cylinder with piston another return stroke follows whereby the exhaust gases are forced out throupgh the tubes 23 and 24 of the exhaust'device'; This cylinder traveling farther reaches a point near the end of the enlarged exhaust space Where the piston expels the last traces of the exhaust gases by extending somewhat beyond the cylinder opening. These traces and the fresh air entering through the inlets 7 are expelled by the draft of the outrushing bulk of the waste gases. On continued rotation the cylinder again reaches the fuel inlet 5 whereby the cycle of rotation is completed. The other cylinders perform the samecycle of operations, one after another and the explosions take place in quick succession. It

is self-evident that only pure gas mixtures are sucked into the cylinders. A. sufliciently long suction takes place without creating a partial vacuum. The compression of the mixtures proceeds slowly and without great resistance. The piston then is kept briefly in its position by the roll in the cam groove allowing a complete ignition of the explosive gas mixture before the power stroke begins. Thus the piston has a special period of ignition between the compression period and the power stroke owing to the cam groove arrangement whereby any back pressure is avoided. The explosion causes an immediate action and the transmission mechanism fully utilizes the produced power as it has no dead centers and operates from beginning to end. Side pressure of the piston is avoided because its rod mores nearly in a straight line. The power period may be prolonged at will whereby full use of the great tension of the gases is made, and the cylinders and exhaust devicesare perfectly cleansed during each revolution of the motor. Although the described motor presents all the desired advantages I do not limit myself to the particular construction of the details and various changes may be made without departing from the spirit of this invention which is characterized mainly by the'rot-ation of one part on another whose spherical surface portions make it possible to effect a perfect packing by means of the packing rings with conforming surfaces and the use of the cam With eccentric groove which may be specially constructed for motors for various applications. Accordingly various parts may he dillerently al-ranged and stationary pa rte made rotatable and vice versa.
